中文摘要：

投影算法能较好地从宏观层面把握数据序列的接近程度,灰色关联度又恰恰可以反映数据曲线几何形状的相似性,结合投影算法和灰色关联度法的优点,弥补两种方法存在的不足,将这两种方法集成,构造出一种新的相对贴近度作为判断方案优劣的标准,提高了决策结果的可信度,避免了只引用其中某一种方案进行决策的片面性、局限性,并通过实例验证了可行性.

英文摘要：

projection algorithm can well from a macro level to grasp the close degree of data sequences, the grey correlation degree can precisely reflect the data curve geometry similarity, In this paper, the advantages of combining projection algorithm and the method of grey correlation degree, make up for the deficiency existing in the two methods, integrate the two methods, construct a new kind of relative closeness as a standard of evaluating scheme, improve the credibility of the decision results, avoid the reference only one kind of scheme to make decisions of one-sidedness and limitations, and feasibility is verified by examples.
